It's not solely for men. In fact, I firmly believe that women can derive just as much benefit from learning about their own bodies and pleasure points.
Understanding one's own body is a crucial aspect of sexual health and satisfaction for both genders. When women take the time to explore and discover their unique erogenous zones and what brings them pleasure, they are better able to communicate their desires and preferences to their partners.
Now, instead of using vague phrases like "Yeah more of that!" or "Um... try something different," I can have more informed and specific conversations with my partner. This not only enhances the quality of our sexual experiences but also deepens our connection and intimacy.
Lots of useful information can be found within this text, despite its gratingly exuberant writing style. Almost every rhetorical flourish is cringe-inducing to such an extent that it makes one want to discard the book. The noisy odes to the overrated Strunk and White make it nearly impossible to progress beyond the first chapter.
However, it does possess very good details and ideas. Although, it can be a bit rigid or ideological on numerous points. Thankfully, I will never have to date this individual, but I don't mind extracting knowledge from his base. It is much more anatomically specific and detailed than Violet Blue's collection. Nevertheless, it is much less sincerely spirited. Seriously, all of Kerner's over-enthusiasm reeks of someone trying overly hard to compensate for something, similar to a desperate motivational speaker.
It is worth rereading in conjunction with other titles from the genre. Definitely not the Bible, but it is extremely useful for many men and women. The programmatic/formulaic approach he presents might not be especially useful, but culling from the base of information and methods presented does yield benefits.
